Other forms: bailed out; bailing out; bails out
To bail out is to remove water from a boat by scooping it. You'll have to bail out that rowboat and patch those holes in the bottom before you head out on your adventure!
If you bail out the canoe while your friend paddles, you're helping to stop it (and you) from sinking. And if you bail out someone who's in jail, you help them by paying the fee — known as bail — required to keep them from spending the night in a cell. You can also figuratively bail someone out, just by helping them out of a difficult situation: “Thanks for bailing me out when I forgot my lunch money!”
